x =
Step-by-step explanation:
10 = + * x
10 = + ()²x
10 = + * x
x =
Answer:
= 12, = 10
Step-by-step explanation:
Given that:
Number of pennies =
Total amount in pennies = cents
Number of nickels =
Total amount in nickels = 5 cents
Number of coins are not less than 20.
i.e. the inequality can be written as:
Total money is not more than $0.75 i.e. 75 cents
The inequality can be written as:
...... (2)
Also, the number of nickels and pennies must be in positive numbers.
Therefore,
When plotted in graph, we get the image as attached in the answer area.
Solution of the graph is the area which is common to both the lines.
And one solution between them is (12, 10)
i.e. number of pennies, = 12
Number of nickels, = 10
The distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.
<h3>Circumference, diameter and radius</h3>
Since the circumference of the CD is about 37.7cm
We can determine the radius of the CD as follows;
Circumference, C = 37.7 = 2 π × r.
However, the diameter of the hole in the center is; 1.5cm, therefore, the radius of the hole in the center is; 1.5/2 = 0.75cm.
Ultimately, the distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.
